CONTROL DEVICE HAVING A NIGHT LIGHT
First Claim
1. A control device having a night light, the control device adapted to control an electrical load receiving power from a power source, the control device comprising:
- a controller for controlling the electrical load;
at least one control element coupled to the controller, the control element generating a signal when activated to cause the controller to control the electrical load; and
a night-light circuit comprising an LED for illuminating the night light, the LED having a normal operating current range;
wherein the night-light circuit is operable to conduct an LED current through the LED to illuminate the LED, the LED current having a magnitude several orders of magnitude below the normal operating current range.

Abstract
A battery-powered remote control for radiating wireless signals to control a controlled device has a night light that glows whereby it is visible in a darkened room and the battery lasts at least about three years. It also includes a wireless transmitter, a controller, a battery and a control element. The control element generates a signal when activated to cause the controller to operate the wireless transmitter to transmit a wireless signal to control the controlled device. The night light comprises a light emitting diode and a light pipe having a textured front surface. A power supply circuit for the LED provides an LED current from the battery. The LED has a normal operating current range and the LED current is several orders of magnitude below the normal operating current range.
